To (LU 10/1/0721, it vita/y concern:

Be it known that I, Louis L. MARTIN, ma chinist, of the city of Toronto,in the county of York, Province of Ontario, Canada, have inventedcertain new and useful Improvements in Coin-Controlled Apparatus forVending Perfumes and other Liquids, of Which the following is aspecification.

The object of my invention. is to devise a jet-pump for vending perfumeadapted particularly for use with coin-controlled apparatus; and itconsists, essentially, of a receptacle, a pump-barrel located within thereceptacle and having one or more apertures in its sides, a plug securedwithin one end of the barrel and provided with a fine bore, a plungerfitted within the barrel and having its inner end adapted to close thebore in the plug, and a spring tending to maintain the plunger againstthe plug, substantially as hereinafter more specifically described andthen definitely claimed.

Figure 1 is a side sectional elevation of my invention. Fig. 2 is asectional plan of the pump-barrel and plunger.

In the drawings like letters of reference indicate the correspondingparts in the different figures.

This application is filed as a division of application, Serial No.203,340, filed April 15, 1904:, and the constructions describedhereinafter are intended particularly for use with the coin-controlledapparatus set out in that application.

I is a scent-receptacle. Within the scent-receptacle is secured thepump-barrel J, one end of which projects out from the forward end of thereceptacle. Secured within this end is the plug 72., having a fine boreextending through it from end to end and communication with the interiorof the pump-barrel. A small tube K connects with the bore in the plugand serves to direct the jet of liquid discharged by the pump, ashereinafter described. The inner end of the plug is preferablyconeshaped, as indicated. Through the sides of the pump-barrel and nearthe inner end of the plug are formed one or more small apertures t',through which the perfume enters the interior of the pump-barrel. Whileone aperture if sufficiently long would suffice, I prefer to employ twoor more set at varying distances from the plug it. The plunger L fitseasily Within the pump-barrel, and its end is preferably provided with asmall plug or insert j, of leather or other soft material,

which is adapted to close the bore in the plug when the parts are in theposition shown in the drawings.

An operating-rod M is secured to or formed integral with the plunger,and its end is ex tended out through the rear of the scent-receptacle.The end of the operating-rod is provided with a small journaledfriction-roller A), intended to be operated by the coin-controlledmechanism described in the application hereinbefore referred to. Thecoil-spring Z, secured to the scent-receptacle and the op crating-rodand plunger, tends to maintain the parts in their normal position.

The operation of the device is substantially as follows: By drawing backthe operatingrod M one or more of the holes 6 will be uncovered to agreater or less extent, permitting a proportionate quantity of perfumeto enter the pump-barrel. When the operating-rod is returned to itsnormal position by means of the spring l, a small jet of liquid isejected through the bore in the plug It. While of course a certainquantity of the scent is likely to be ejected through theinlet-apertures 2', yet the larger quantity will pass through the borein the plug, as described.

As the plunger is normally held tightly in contact with the end of theplug by the spring, the outlet is always tightly closed, the softleatherinsert making a liquid-proof joint.

The merits of this pump for coin-controlled vending apparatus lie in itsextreme simplicity and cheapness of construction, also in the facilitywith which the output can be regulated by regulating the backwardmovement of the plunger.

What I claim as my invention is 1. In vending apparatus, the combinationof a pump-barrel having a closed end provided with a fine bore and anaperture in its side; a plunger fitted within the barrel and having itsinner end adapted to close the bore in the end of the barrel; and aspring tending to maintain the plunger against the end provided with thefine bore, substantially as described.

2. In vending apparatus, the combination of a pump-barrel having anaperture in its side; a plug secured within the said end of the barrelhaving an aperture therein; a plunger fitted within the barrel andhaving its inner end provided with a soft insert adapted to close theaperture in the plug; and a spring tending to maintain the plungeragainst the plug, substantially as described.

3. In vending apparatus, the combination of a liquid-receptacle; apump-bar rel. located Within said receptacle and having one aperture inits side; aplug secured Within one end of the barrel and provided with afine bore;

a plunger fitted within the barrel and having its inner end adapted toclose the bore in the plug; a spring tending to maintain the plungeragainstthe plug; and an operating-arm for the plunger extending-outsidethe receptacle, substantially as described. a

4. In Vending appa.ratus,.the; combination of a pump-barrel having a;plurality of apertures formed therein at varying distances from the end;a plug secured Within the said end and provided with a fine bore; aplunger fitted within the barrel and having its inner end adapted toclose the bore in the plug; and a spring tending to maintain the plungeragainst the plug, substantially as described.
